CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 251,366, dated December2'?, 1881.

Application filed July 21, 1881. (No model.)

To all whom it may concern:

Be it known that I, DANIEL KEETHLEE, of Mount Oreb, Brown county, Ohio,have invented certain new and useful Improvements in Oar-Couplings, ofwhich the following is a specification.

The tirst part of my improvements comprises a novel combination ofsheave and crossed ropes or chains, whereby the coupling-pin can beraised without compelling the coupler to pass in between the cars, ashereinafter more fully described.

The second part of my invention consists in journaling the aforesaidsheave in a pair of standards projecting from the top of the drawhead,the front surface of the rear standard being so inclined or sloped as toguide the T-head of the coupling-pin directly into a recess in saiddraw-head, as hereinafter more fully described.

In the annexed drawings, Figure 1 is a vertical section of mycar-coupling. Fig. 2 is a horizontal section of the same, the link beingshown in the act of entering the draw-head. Fig. 3 is a transversesection of the upper part ofthe coupling, taken in the plane of theT-head of the pin.

The draw-head A is provided with a customary haring mouth, B, that opensinto the chamber of said head, the side walls, O O', of this chamberbeing concaved, as more clearly shown in Fig. 2. The roof D of thisconcave chamber slopes, as seen in Fig. 1, and is grooved or hollowedout at E to permit free backward swing of the coupling-pin F, whichlatter device has a Tshaped head, G, as more clearly shown in Fig. 3.Attached to this head G is one end of a rope or chain or other flexibleconnection, H, which, after passing over a sheave or roller, I, iscarried out to the side of the car, and has its other end secured in anysuitable manner. H' is another cord or chain, applied in a similarmanner, but extending to the opposite sideof the car. Roller I isjournaled on a bolt, J, or on a pin capable of being readily removed,said pivot being applied to two standards, K K', projecting upwardlyfrom the draw-head A. The rear side of the front standard, K, isrecessed at L, to admit the head G of the pin F, and thereby prevent thelatter being jolted out of the drawhead.

The oor N 'of the concave chamber slopes rearwardly, as shown, and isgrooved or hollowed out at Oto allow the piu F to swing therein.

v .P is an ordinary coupling-link.

When my coupling is in its normal position the head G enters the recessL, and thus prevents any accidental disengagement of the pin F by thejolting of the cars or otherwise. As soon, however, as it is desired todisengage the link P the coupler has only to pull on either of the cordsH or H', which act launches rearwardly the lhead G, on account of thefront surface of standard K' being inclined in the manner shown in Fig.l. Consequently the pin F is at once disengaged from said link, andwithout compelling the coupler to enter between the cars, and therebyendanger his life. When the link P first enters, the head G turns in itsrecess or socket L and allows the pin F to swing rearwardly up into theslot E; but as soon as the link is in position said pin swings downintothe slot O and is at once ready for anystrains that may be broughtto bear against it. In case the link should enter in the oblique mannerrepresented in Fig. 2, the concave wall O will guide said link properlyand cause it to take such a path as to insure its engagement with thepin F; or practically the same results may be effected by forming thewalls of said chamber with obtuse angles, as indicated by the dottedlines in Fig. 2.

I claim as my invention- 1. In combination with a vertically-shil'tablecoupling-pin, the roller I and crossed chains or ropes H H', for thepurpose specified.

2. ln combination withacoupling-pin, F G, operating ropes or chains HH', and roller I J, the standards K K', of which the front surface ofstandard K' slopes in the manner shown, and for the purpose stated.

3. An improved draw-head, consisting of the mouth B, concave chamber CC' D N, grooves E O, swinging pin F G, crossed ropes or chains H H',sheave I, standards K K', and recess L, which latter receives the head Gof said pin, as herein described and set forth.V

In testimony whereof I affix my signature in presence of two witnesses.

DANIEL KEETHLER.
